Claude Fable 5.2 cracked a black-hole calculation that physicists had left unfinished for 23 years.
A physicist has already checked the work, i.e. this is new knowledge in fundamental physics that came largely from an AI.
In 1983, Stephen Hawking and Don Page showed that when a certain kind of universe heats up, a black hole forms suddenly, like water hitting boiling point, but their method only worked for large universes.
In 2003, physicists laid out the calculation needed for tiny universes, but it was so long and tedious that nobody finished it, until Claude did it largely on its own and found that black holes form suddenly there too.
Fable 5.2 solved two open problems in theoretical physics related to black holes.
In the first, Fable 5.2 completed a laborious calculation that had gone unsolved for 23 years. https://t.co/BdxZ7NkvhT

One problem asks how to time 42 trains to cut peak power use. In under two hours, agents beat MIPLIB’s best timetable by 2.6%, and later proved no better timetable exists.
We’ve submitted the solutions to MIPLIB for anyone to check.
